TROLLEY GUARD.

Application filed December 9, 1924. Serial No. 754,861.

To all whom it may concern:

Be it known that I, lVILsoN K. PAGE, a citizen of the United States, residing at ()lean, in the county of Cattaraugus and State of New York, have invented a new and useful Trolley Guard, of which the following is a specification.

This invention relates to trolley guards and is designed more especially as an improvement upon the structure disclosed inv Patent No. 768,480 issued to 1118.

Heretofore it has been the practice to provide trolley guards in the form of elongated strips of coarse metal fabric which have been supported loi'igitudinally over trolley wires at railroad ci.'r. ssings and other points of danger so that should the trolley wheel leave the wire, it would come into contact with the: wirefabric of the guard which, being electrically connected to the trolley wire or other source ofelectricity,

will allow current to continue to flow to the motor of the car, thereby avoiding all danger of the car becoming stalled at the crossi'ng.

The guards thus far made and used have ordinarily been in one dong piece which, after being delivered at. the pointof use, have been shaped before being suspended in place. This lnis'obviously increased the cost of setting up the guard because of the time and labor involved. The cost of transporting the guard has also been objectionable because the guard has necessarily been shipped in roll form.

. SUlflIlQfl'ODl the use of the one-piece eloni new length.

gated guard is the fact that, after long continued use, those portions of the guard located above the tracks of the .railioad crossed. thereby become corroded from the Another object is to provide a sectional guard, the ends of which can be securely fastened together by simple means provided Another objection re-.

for that purpose, said ends being so supported that the trolley wheel cannot become hung thereon while passing along the guard.

Another object is to provide a guard made upof interchangeable sections so that'should one or more of the sections become corroded,

or otherwise unlit for use, a new section can be substituted therefor without the necessity of taking. down the entire guard or replacing any part other than the faulty section.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the coinbination and arrangement of parts and in the details of construction hereinafter described and claimed, it being changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without understood that departing from the spirit of the invention.

In the accompanyingdrawings thepreferred' form of the invention has been shown.

in said drawings Figure 1. is a bottom plan view of two connected sections of a guard constructed in accordance with thepresent invention, portions of said sections being broken away.

Fig. 2 is a central vertical section through the meeting portions of the guards.

. Fig. 3 is a plan view of the meeting portions of the two sections separated.

Fig. i is a section on line -i-i, Fig. 1. Fig. 5 is a section on line 5+5, Fig. l. Referring to the figures by characters of reference 1 designates side rods to which are connected the side portions of the coarse i wire fabric 2. this fabric being bowed trans versely as, shown. The side rods 1 are con nected', at one end, by a bowed cross rod 3 and the corner portions of that end of the wire fabric extending up to these cross rods are cut away diagonally as shown at i in Fig. 1, leaving tie end portions of the two rods 1 clear for a short distance between the fabric and the cross rod The other end of the fabric has its corner portions cut. away as shown at 5 in Fig. 3 but the ends of the side rods 1 extend the full length of the section as shown, projecting beyond the fabric.

. The separate sections of the guard are adapted be placed end to end with the projecting ends of thesiderods 1 lapping as shown particularly in Fig. 2. The transverse connecting rod 3 at one of these ineeting ends of the guard is extended under the jn'ojec-ting fabric on the other guard section. In other words that portion of the guard shown at the left. of Fig. 3 is adapted to be positioned beneath that portion of the guard shown at the right of Fig. 3. With the two sections thus assembled, an arcuate supporting yoke (S is placed transversely over the lapping portions as shown in Figs. 1. and 4-. This yoke is channeled longitudinally and has a central opening 7 for the reception of a suitable;connection whereby the yoke can be suspended from a suitable supporting structure. The ends of the yoke are formed with apertures S and these apertures are designed to receive the inner sides of U-bolts 9 which are sufficiently large to straddle the lapping rods 1. On each U- bolt is mounted a. block 10 having a recess 11 in the bottom thereof into which the rods 1 project and this block has separate openings 12 through which the sides of the U-bolt extends; By tighteniug'the Ubolts with nuts 13 engaging the end portions thereof, the lapping rods 1 can be clamped tightly within the groove or recess ll and at the same time the'blocks 10 as well as the rods 1 will be fastened securely to the ends of the yoke 6. Thus it will be seen that each U- bolt serves not only to bind together the lapping rods and those holding the two sections in proper relation to each other, but also to secure the sections to the supporting yoke.

As has already been pointed out, the sections making up a trolley guard are adapted to be nested and while so arranged, can be shipped readily. In setting up-the guard, the sections are placed in lapped relation with the rods 3 extending under the adjoining section as already pointed out. The yokes are then placed astride the sections and attached to suitable supports. Should one or more of the sections become corroded or otherwise damaged so as to make it desirable to remove the same, it becomes neces sary to disconnect the one section and re-- place it with another. Obviously, therefore, the removal of the complete guard for the purpose of making repairs is not essential and consequently the cost of upkeep is greatly reduced.

hat is claimed is j 1. A. trolley wire guard comprising detachably connected sections adapted to nest, said sections having lapping ends, and means engaging the end portions of the sections for binding them together.

2. A. trolley wire guard including trans versely bowed sections of cross metal fabric adapted to nest, said sections having lapping end portions, an arcuate rod at one end of one section extending under the lapping portion of the next adjoining section, side rods forming parts of the sections and projecting beyond the fabric, and means for binding them together to hold the extensions in operative relation.

A trolley wire guard including similar sections adapted to nest, each section including a cross metal fabric arched transversely and having parallel, reinforcing rods at the sides and an arcuate transverse connecting rod at one end, the end portions of the side rods of each section being adapted to lap the end portions of the side rods of the next adjoining sections, a supporting yoke straddling the lapping'portions of the sections, and means engaging the end portions of the yoke for binding together the lappingportions of the rods and attaching the yoke to said portions.

4:. A guard for trolley wires including sections of cross metal fabric, each section being bowed transversely andhaving reinforcing side rods and a transverse bowed end rod, said sections adapted to nest and normally positioned with their ends lap-- ping, an arcuate supporting yoke straddling the lapping portions of the sections, recessed blocks extending into the yoke, each block receiving the lapping rods of the adjoining sections, and U-bolts straddling the lapping rods andextending through the blocks, said bolts engaging theyoke and constituting means for holding the rods, block and the yoke assembled.

5. A trolley wire guard including similar sections of cross metal fabric, each section being bowed transversely, said sectionsv having lapping ends, side rods forming parts of the sections and having projecting ends, supporting yoke straddling the lapping portions of the side rods, and means for binding said rods to the yoke.

6. A trolley wire guard comprising a supporting yoke, transversely arched guard sections adapted to nest but normally positioned with their ends lapping under the yoke, and means for binding'the lapping ends of the sections to the ends-of the yoke.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
